GLOSURE FOR FRUIT-JARS.

Specification of Letters Patent.

Patented Aug. `*7, 1 91 '7.

Application filed February 16, 1915. Serial No. 8,574.

To all 'whom 'it may concern:

Be it known that l, NELLIE HAILER, a citizen of the United States,residing at Slatington, in the county of Lehigh and State ofPennsylvania, have invented new and usef'ul Improvements in Closures forFruit- J ars, of which the following is a specification.

This invention relates to closures for :fruit jars or like receptacles.

The primary object of the invention is to provide a closure for fruitjars and similar receptacles in which a clamp for holding a closing capin contact with a packing bearing on the neck of the receptacle isformed from a pair of resilient clamp sections so shaped and connectedas te permit independent adjustment of the clamp sections to more firmlyengage the cap with the packing.

The invention consists in the improved construction7 novel arrangementand combination of parts which will be hereinafter fully described andparticularly pointed out in the claim.

The preferred embodiment of the invention has been illustrated in theaccompanying drawing, but no restriction is necessarily made to theprecise details of construction therein shown, as changes, alterationsand modifications within the scope of the claim may be resorted to whendesired.

ln the drawings Figure 1 is a side elevation of a portion of a fruit jarshowing my invention applied thereto.

Fig. 2 is a top plan view of the same.

Fig. 3 is a sectional view on the line 3-3 of Fig. 2.

Fig. 4 is a detail perspective view of the jar closure or cap.

Fig. 5 is a detail perspective view of the clamping member.

Like characters of reference denote corresponding parts throughout theseveral views.

The numeral 1 designates a fruit jar of ordinary well known type havingan upstanding annular neck 2 provided with the usual threads 3.

A disk Aor closure member 4 for insertion within the neck 2 and having adiameter slightly less than the inside diameter of the neck 2 isprovided in its periphery with a circumferentially extending groove 5having an inclined wall 5 and a straight wall 5, said groove providingthe disk at one end with a laterally extending flange 6 serving as aseat for a packing 7 arranged within said groove and adapted to engagethe inner wall of the neck and to bear upon the rim thereof to support`the disk or closure member within the neck of the receptacle. The edgeat the inner end of the disk, or closure member 4 is rounded to providea bead 9 engaging the packing 7 above the neck of the receptacle. Oneend 11 of the disk or closure member 4 has formed therein a recess 12 topermit a clamping member 13 to engage with the neck of the liar to bearon the bead 9 and hold the same firmly engaged with the packing 7.

The clamping member 13 comprises a pair of clamp sections 13 and 13,each formed from a strip of resilient material bent between its ends toform a V-shaped body portion and to extend within said recess to providea handle by means of which said receptacle may be lifted, said stripsbeing twisted intermediate their end to form interengaging eyes 14,whereby the clamp `sections are hingedly connected and independentlymovable circumferentially about the closure member 4. The ends of theclamp sections 13 and 13 are bent to form fingers 15 of unequal lengths,that is to say, the finger 16 of the clamp section 13 is of greaterlength than the finger 17 of the clamp section 13, so that these fingerswhen engaged with the threads 3 upon the neck 2 of the jar or receptaclewill maintain the closure member 4 in a sealed position.

From the foregoing'description taken in connection with the accompanyingdrawing it will be clearly seen that when the closure member 4 isinserted within the neck 2 of the jar or receptacle 1, the packing orgasket 7 is seated upon the mouth of the jar by the bead 9 on theclosure member and an effectual stopper is provided. By the insertion ofthe closure member 4 within the neck of the jar the fruit therein may beforced down into the liquid surrounding the same and the liquid broughtfiush with the bottom of' the closure member 4 while the liquid is in aheated condition.

TWhen the clamping member 13 is engaged with the threads 3 upon the jar1 the bead forces the gasket 7 against the mouth of the jar, and throughthis action the gasket 7 is spread out into the recess 6 thereby wedgingthe closure 4 more tightly within the mouth 2 of the receptacle 1..

Upon the cooling of the contents of the jar the vacuum formed thereinbetween the bottom of the closure 4 and the contents of the jar allowsthe atmospheric pressure upon the closure 4 to force the same stillfarther within the neck oit' the jar, thereby causing the liquid held bycapillary attraction at the point of Contact of the flange 5 with theneck 2 to expand and hermetically seal the jar so that the leakage ofair into the receptacle is prevented.

. Vhen the clamping member 13 has been applied to the neck of thereceptacle to retain the closure member therein, it will be seen withreference to Fig. 2 in the drawing that either clamp section may bemoved circumferentially about the closure member and neck of thereceptacle to cause the iingers on the section through their engagementwith the threads on the neck of the receptacle to force the closuremember more deeply within the neck, thus insuring the packing 8 formingan air-tight joint between the neck of the receptacle and the closuremember.

Having thus described the invention what is claimed as new, is

In a device of the class described, a receptacle having a neck, aclosure member slightly less in diameter than the inside diameter of theneck and extending therein, said closure member having acircumferentially extending groove in its periphery providing theclosure member at one end with a laterally extending iange, a packing insaid groove engaging said flange and the neck of the receptacle tosupport said closure lnember therein, and a bead at the other end of theclosure member engaging said packing above the neck of the receptacle.

In testimony whereof I ailix my signature in presence of two witnesses.
